Another option for the block heater plug would be for you to go out and buy a marine plug and mount that in your bumper. I forget the name of the plugs but they look like a trailer plug in but just will the normal prongs like and extension cord. Easy to plug in and then the prongs don't get all corroded cause they are overed
